A high‐temperature oxide electrolyte galvanic cell of the type , , O 2 is described. Experimental data for reaction of oxygen with hydrogen‐water and methane‐water mixtures are given. Open‐circuit voltages for the hydrogen‐oxygen reaction are close to theoretical, and current‐voltage curves show that the output of the cell is limited essentially by the resistance of the electrolyte. The data suggest that solid oxide electrolyte cells of this general type may offer attractive possibilities as fuel cells for utilizing hydrocarbons as fuel and oxygen or air as oxidant.
